Description

Technical Field

[0001] The present application relates to the field of condensers, and in particular to a new composite condenser with side air outlet. Background Art

[0002] According to the different cooling media and cooling methods, commonly used condensers can generally be divided into water-cooled and evaporative types. The water-cooled condenser immerses the finned tubes in water and directly transfers the heat of the finned tubes to the water for cooling. The evaporative condenser uses a spraying method to form a water film on the finned tubes. As the water film evaporates, it absorbs heat, thereby cooling the finned tubes.

[0003] Water cooling and evaporation are often used together. Some finned tubes are immersed in cooling water for direct heat exchange, while the other finned tubes are sprayed to further dissipate heat through water evaporation. This achieves a better cooling effect.

[0004] However, the existing water cooling and evaporative methods are combined together, but both work independently. For the water cooling, the cooling water with a higher temperature needs to be discharged after heat exchange; for the evaporative method, the finned tubes are sprayed by an external water source. It is just a simple combination without further combination. Although the cooling effect is better than that of the single water cooling and evaporative methods, it is still necessary to process the cooling water after heat exchange in the water cooling method and find an external water source in the evaporative method.

[0005] In view of the above-mentioned related technologies, the inventors believe that it is necessary to design a method that can conveniently solve the problem of cooling water treatment after heat exchange in water-cooled type and the problem of finding an external water source in evaporative type. Summary of the invention

[0006] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art, to conveniently solve the problem of cooling water treatment after heat exchange in water-cooled type and the problem of finding an external water source in evaporative type, and to provide a new condenser with side air outlet.

[0007] In order to achieve the above purpose, this application adopts the following technical solutions:

[0009] Preferably, the shell is provided with an air supply duct, the air supply duct is installed with a fan, the fan has an air supply port, and the air supply port is communicated with the spray chamber.

[0010] Preferably, the side wall of the shell is also provided with an air inlet, and a dust cover is installed at the air inlet.

[0011] Preferably, a cam is rotatably provided in the water-cooling chamber, and the cam abuts against the upper surface of the lower pressure plate.

[0012] Preferably, a return spring is provided between the lower surface of the lower pressure plate and the bottom of the water cooling chamber.

[0013] Preferably, a guide protrusion is fixed to the side wall of the water-cooling chamber, and the guide protrusion is slidably connected to the lower pressure plate.

[0014] Preferably, the lower pressure plate has a water outlet, and the one-way valve is a sealing plate rotatably arranged on the lower surface of the lower pressure plate, and the sealing plate is located at one end of the water outlet.

[0015] Preferably, the bottom of the spray chamber has a water trough, a water return pipe is provided between the water trough and the water cooling chamber, and a water pump is built in the water return pipe.

The original water-cooling and evaporation modes work independently, but now the water-cooling and evaporation modes are connected and interact with each other, thus solving the problem of cooling water treatment after heat exchange in the water-cooling mode and the problem of finding an external water source in the evaporation mode.

[0025] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0026] The embodiment of the present application discloses a new type of condenser with side air outlet.

[0027] Reference Figure 1 A new type of condenser with side air outlet includes a shell 1, a water cooling chamber 11 and a spray chamber 13 are provided inside the shell 1, the water cooling chamber 11 is located directly above the spray chamber 13, a first fin tube group 12 is installed in the water cooling chamber 11, a second fin tube group 14 is installed in the spray chamber 13, and the output end of the first fin tube group 12 is connected to the input end of the second fin tube group 14. The fluid to be cooled will first pass through the first fin tube group 12 to be water-cooled, and then pass through the second fin tube group 14 to be spray-cooled.

[0028] Reference Figure 2 and Figure 3 A lower pressure plate 2 is slidably provided at the lower part of the water cooling chamber 11, and a one-way valve is provided on the lower pressure plate 2. A spray pipe 21 is connected to the bottom of the water cooling chamber 11. The spray pipe 21 passes through the shell 1 and one end with a spray head is located at the top of the spray chamber 13.

[0029] A sealing ring is provided between the lower pressing plate 2 and the side wall of the water cooling chamber 11. When the lower pressing plate 2 moves upward, the one-way valve allows the water on the upper part of the lower pressing plate 2 to enter the lower part of the lower pressing plate 2. When the lower pressing plate 2 moves downward, the one-way valve is closed, which prevents the water flow under the lower pressing plate 2 from flowing back to the upper part of the lower pressing plate 2 on the one hand, and on the other hand, the water flow under the lower pressing plate 2 will spray the second fin tube group 14 in the spray chamber 13 through the spray pipe 21.

[0030] A guide protrusion 24 is fixed to the side wall of the water-cooling chamber 11, and the guide protrusion 24 is slidably connected to the lower pressing plate 2. The lower pressing plate 2 can slide along the length direction of the guide protrusion 24, and the lower pressing plate 2 reciprocates up and down in the present application.

[0031] A cam 22 is rotatably provided in the water-cooling chamber 11, and the cam 22 abuts against the upper surface of the lower pressure plate 2. The housing 1 is equipped with a motor connected to the cam 22, which is not shown in the figure. When the cam 22 rotates, it can push the lower pressure plate 2 to move downward. A return spring 23 is fixedly connected between the lower surface of the lower pressure plate 2 and the bottom of the water-cooling chamber 11, and the return spring 23 can push the lower pressure plate 2 to move upward. Through reciprocating motion, the water in the water-cooling chamber 11 is pumped into the spray chamber 13.

[0032] The lower pressing plate 2 has a water opening 25, and the one-way valve is a sealing plate 26 rotatably arranged on the lower surface of the lower pressing plate 2. The sealing plate 26 is rotatably connected to the lower surface of the lower pressing plate 2 by a torsion spring, and the sealing plate 26 is located at the lower end of the water opening 25. When the lower pressing plate 2 moves upward, the water on the upper part of the lower pressing plate 2 will pass through the water opening 25 and push the sealing plate 26 to rotate, so that the water on the upper part of the lower pressing plate 2 enters the lower part of the lower pressing plate 2. When the lower pressing plate 2 moves downward, the sealing plate 26 will block the water opening 25, and at this time, the lower pressing plate 2 can press the water below, so that the water below the lower pressing plate 2 sprays the second fin tube group 14 through the spray pipe 21.

[0033] The housing 1 is provided with an air supply duct 3 , and a fan 31 is installed in the air supply duct 3 . The fan 31 has an air supply port 32 . The opening of the air supply port 32 faces downward and is communicated with the spray chamber 13 .

[0034] The side wall of the shell 1 is also provided with an air inlet 16. In the present application, there are two air inlets 16, which are respectively located on both sides of the shell 1. A dust cover 17 is installed at the air inlet 16. The air inlet 16 has an air inlet area 18. The air inlet area 18 will generate negative pressure. The dust cover 17 can filter out some dust in the process of the air in the air inlet area 18 entering the air supply duct 3.

[0035] An air outlet 15 connected to the spray chamber 13 is provided on the side of the shell 1. After the air from the air supply port 32 passes through the spray chamber 13, the water on the second fin tube group 14 will be evaporated faster, and the evaporated hot air will flow away from the air outlet 15.

[0036] The bottom of the spray chamber 13 is provided with a water trough 4, and a return pipe 41 is provided between the water trough 4 and the water cooling chamber 11, and a water pump is built into the return pipe 41. Part of the return pipe 41 is located in the air inlet area 18, and the negative pressure generated in the air inlet area 18 will also increase the air flow near the return pipe 41, thereby cooling the return pipe 41. The water trough 4 is provided with a water level monitor 42, and the water level monitor 42 is built with a signal analysis module and a signal transmission module. The water pump has a signal control module and a signal receiving module. When the amount of water in the water trough 4 is large, it is detected and identified by the signal analysis module, and then the signal transmission module will transmit the signal to the signal receiving module of the water pump. After the signal receiving module receives the signal, it can let the signal control module control the water pump to start. Under the action of the water pump, the water in the water trough 4 can enter the water cooling chamber 11 through the return pipe 41.

[0037] The implementation principle of the embodiment is as follows: first add water to the water-cooling chamber 11 so that the first fin tube group 12 is submerged in water, and heat exchange can be achieved. As the water temperature in the water-cooling chamber 11 gradually increases, the lower pressure plate 2 can move up and down, allowing the water with a higher temperature to enter under the lower pressure plate 2, and the new cold water will cool down the first fin tube group 12 again. The water with a higher temperature will enter the spray chamber 13 through the spray pipe 21 under the pressure of the lower pressure plate 2. After the spray pipe 21 sprays the second fin tube group 14, a layer of water film will be formed on the surface of the second fin tube group 14. Under the blowing of the fan 31, the air near the water film can flow quickly, thereby improving the evaporation effect of the water film, thereby improving the cooling of the second fin tube group 14 in the spray chamber 13.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application; therefore, according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the above specific implementation modes and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention. Therefore: All equivalent changes made according to the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
